Of course the strip is wank, its an old airfiled that cant be touched! Drag radials will give a little bit more at Crail but not much. Semi slicks will give good gains, R888, A048 etc etc. Crails only slow because folk dont know how to drive to diffirent conditions/tracks. ;) I managed 1.9 60ft last time i was there on semi slick tyres 13 sec flat pass with a fluffed gear change in a 250WHP motor..
